s claims. (o1. 2484-7) v n A The present invention relates to stands or supports for lamps and the like, and has for arrobject to provide anvfimprovedcoupling and-'holding device for adjustably and yieldablyholding crossedv members together, kso that the latter may be relatively adjusted lengthwise of the members to accommodate the stand to various heights and other, conditions. n 1

Another object .ofk the present inventionV is ,to providea lamp stand having a standard anda cross arm with a resilient coupling `device arranged to slidablyv and frictionally embrace both the standard andthe ,cross arm so that the cross arm with the device may be slid vertically on the standard into different heights and be yieldably held in adjusted position as to height, and wherein the cross` arm may .be slidagainstthe standard and the coupling device so as izo-,project 4rthe cross arm into various distances from the standard so that vthe cross arm will be yieldably held in such adjusted position.- j f The invention has for a further object the provisionof aring-likejresilient device which may be made in one piece and be easily assembled with respect to the crossed members of a stand or support, and which is adapted for various configurations for ornamental and like purposes and which will hold the crossed members at a desired angle and yieldingly maintain the members in relatively 1adjusted positions relative to their crossed posiions.

'Ihe invention also aims to provide a simplified and economical structure which may be utilized in stands, holders or supports of various constructions for lamps, flower racks, bird cages, telephones and other uses, and wherein no set screws or other separate fastening devices are required, but wherein the structure o-f the coupling lmember is such as to afford the necessary surface area of frictional contact between the parts -to yieldingly hold them when adjusted.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a perspective View of a lamp stand embodying the features of the present invention and showing the cross arm in one position of adjustment.

Figure 2 is a similar view showing another position of adjustment of the cross arm on the standard.

Figure 3 is a fragmentary enlarged cross'section takeni through the 'upper portion of. the stand on the` line 3 3 of Figure 1, and l Figure 4 is :a detail perspective view of the friction coupling element.

-Referringnow to the drawing, the invention is disclosed in thel present instance as embodied in the lamp'stand having a standard 10 mounted on a base portion 11 of anylsuitable configuration. The stand 10 is of any'suitable height and sup- 10 ports an outstandingifarm 12 which may be disposed horizontally or otherwisein vaccordance With-r; thefrequirement of the stand* or support and which in the present instance may comprise a at bar which .engages across one'side of the 1,5 standard 10, the flatterv being cylindrical or of any suitable configuration.- The arm 12 isshown-in the present instance as carrying a lamp 13 `of any suitable construction Ahaving a lamp-shade 14 and the lamp and its shade maybe supported 20 at any desired height on the standard. 10 and at'any distance outwardly therefrom. 1 The'friction coupling element 15, shown in .detail in Figure 4, comprises a substantially open frame which may be circular or ring shape as 25 shown, or of any other desired conguration. The friction element is provided at opposed points with a pair of laterally depressed or offset sockets 16 having each an inner wall adapted to fit about or against one side of the standard 10 so as to 30 provide the required area extent of frictional contact between the element 15 and the standard 10.

As shown in Figure 3, the sockets 16 embrace the standard 1o sufficiently to provide abutting35 or stop shoulders 17 at opposite sides of the socket to engage the standard and hold the friction element 10 from turning circumferentially thereon in the plane of the element. At intermediate opposed points the frame element 40 15 is provided with sockets 18 which are depressed from the body portion of the element in a direction opposite to that of the sockets 16 and which are shaped to the general configuration of thearm l2 for receiving the arm there- 45 through. The sockets 18 are also of sufiicient depth to provide stop shoulders 19 adapted to engage the opposite edge portions of the arm 12 and hold the holder from turning with respect to the axis of the friction element 15.

From Figure 3, it will be noted that the sockets of the friction element 15 are relatively shallow as compared with the crossed members so that 'the body portion of the friction element 15 when engaged with the crossed members is slightly 55 sprung to yieldingly bind against the outer or remote sides of the crossed elements and thus yieldingly hold the elements in surface Contact at their crossed portions. The body portion of the element 15 is constructed of suitable material and is of sufficient thickness to insure the desired inherent resiliency of the friction element for binding the standard 10 and the arm 12 not only against each other but also in their respective'sockets 16 and 18 off the friction element.

It is apparent that a friction element of this construction may be economically produced by stamping or the like and that the standard 10 and arm 12 may be readily assembled in the friction element as the standard 10 is threaded through its sockets 16 with its exposed side en-l` gaging the exposed side o f the armr12 with reference to the sockets 16 and: 1-8.- Inlother Words;

the standard 10 holds the arm 12 in thesockets 18 while the arm 12 holds the standard 10 in itsLsockets 16;

'Ifo'.- adjust` the height of the stand.' it isf only necessary to force: the. friction: element: 15v vertically along the: standard 10, while-to; adjust.' the projection of the arm 12 from the:v standard I0 it is only'necessary` toA force. the arm 12Ithrough the friction element. 15. In comparing Figures 1 and.2 of' thedrawing it is;apparent that theV arm 12. may be moveddown' on the standard 10 and at the same time the arm' 1-2 may. be forcedin.- wardly so. as to projectv but. a: short distance from therstandard' 10; Y..

'It is obvious thatK various changes and. modifi'- cationsmay be made in the details of, construction anddesignof thevabove specificallyfdescribed embodiment ofthis invention without departing from thespirit thereof, such changes and modifications being; restricted only bythe'scope of the following-claims.

What is claimed:is:-

1; A. stand` comprising: a. standard', a: flat. arm disposed across one` side off the standard. vand extending` at an angle therefrom, and a friction coupling element having an open central portion with opposed sockets opening through one side of the element to receive the standard and having opposed intermediate sockets opening through the opposite side of the element for receiving the arm therethrough, said intermediate sockets holding the arm against turning about an axis at right angles to the length of the standard.

2. A stand comprising a standard, an arm engaging across one side ofthe standard and having a fiat side confronting the standard, and a friction coupling element comprising a resilient body frame open at its central portion and having opposed socket portions opening through oneA side of the element and engaging against one side of the standard, said body portion having a pair of opposed intermediate sockets opening through. the opposite side of the element and embracing the arm at spaced points from the opposite sides of the standard saidintermediate sockets holding the armagainst turning about an axis at right angles to the lengthl of the standard;

3. A- standfcomprising. a standard ofcylindrical contour, a supporting army having a relatively fiat' body portion engagingl across one side ofv the standard and adapted to be slid vertically on' the standard to dispose thearm-at various heights andi to be slid crosswise of the standard toproject the arm at Vdifferent distancesl from the side of the standard?y and av combined'coupling; holding andl bracing ring threaded over the standard andthe arm and havingopen oppositely facing and alternately disposed bearing portions for engaging the standa-rd and' the arm at spaced pointsdisposed at opposite sides of the point of contact of thestandarclL andi thearm for yieldingly binding the arm against the-standard and frictionally binding both the standard and the arm yieldingly inthe ring.
